Based on the available information, the new season will commence on September 17/18 (depending on the time zone and Epic Game's discretion).While some fans state that things will get delayed, this is an unlikely scenario. Given that the developers are already testing v21.50, everything is on track. Furthermore, with more than a month's time until Chapter 3 Season 3 ends, the developers have ample time to smooth out any issues.2) Bloomwatcher: Antagonist and OutfitAko | Fortnite News@FNChiefAkoUntil her official release, let's call this character..."The Bloomwatcher"Idea suggested by @arknautikore and honestly a fantastic name idea1413124Until her official release, let's call this character..."The Bloomwatcher"Idea suggested by @arknautikore and honestly a fantastic name idea https://t.co/AD5qF0rbXXBloomwatcher, as named by the community, is speculated to be the antagonist of the current season. Although they haven't been officially revealed, players are well aware of their existence. They are likely to make their debut at the end of the current season or the beginning of the next one.Players can expect Bloomwatcher to be added to the Chapter 3 Season 4 Battle Pass if this happens. Much like the Cube Queen, they will be featured as a special skin. They will likely be reactive in nature and may look very similar to the Bloom Outfit.3) Fortnitemares BossWave Prince ❁@WavePrinceFNFortnite are working on interesting Halloween Boss / Creature that has goo effect and "Creature Rise" & "Summon Creatures" abilities.(VIA @HYPEX)Fortnite are working on interesting Halloween Boss / Creature that has goo effect and "Creature Rise" & "Summon Creatures" abilities.(VIA @HYPEX) https://t.co/fVBxEbeFkaOne of the most interesting Fortnite Chapter 3 Season 4 leaks comes from HYPEX. According to him, the developers are working on a unique boss for Halloween, aka Fortnitemares.This new boss/creature will have a "goo" effect and will be able to summon and/or raise creatures, which is a reference to necromancy. Perhaps the boss will be able to reanimate fallen foes such as skeletons or simply summon them in via a rift/portal.4) New Mech: Plate HawkHYPEX@HYPEXEpic began working on a new Character (mech-like) Vehicle codenamed "Plate Hawk" a few updates ago.

It has a blocking ability, primary & secondary fire + it can sprint & reload. Probably for Season 4. Thoughts on what it could be? 🔥 https://t.co/DifL4Ep72xWhat is being hailed as perhaps the most intriguing of Fortnite Chapter 3 Season 4 leaks to date comes from HYPEX. While Mechs are a common sight in-game, this upcoming version seems to be very different, and for good reason. Before readers ask if this is another BRUTE, the answer is no.According to the leaker, this new character (Mech-like) vehicle is codenamed "Plate Hawk." Epic Games began working on it a few updates ago, and it has abilities such as blocking, primary + secondary fire modes, and sprinting. Despite having some information on the subject, no one is sure exactly what it could be.5) New-and-improved Bubble ShieldHYPEX@HYPEXThe Bubble Shield item was updated in the previous update, it can now be properly damaged and destroyed from inside the bubble, and they're working on a challenge for it.It'll most likely return this or next season!3577149The Bubble Shield item was updated in the previous update, it can now be properly damaged and destroyed from inside the bubble, and they're working on a challenge for it.It'll most likely return this or next season! https://t.co/NFZ8nWYJFJThe Bubble Shield is an OG item from Chapter 1 Season X. It functions much like Gibraltar's Dome Shield by blocking incoming and outgoing fire. Those within the dome will get some time to breathe and plan their next move.Although unvaulted in Chapter 3 Season 2, its lifespan was short-lived as it was vaulted again just three days later. Based on multiple Fortnite Chapter 3 Season 4 leaks, the item is likely to get unvaulted next season. HYPEX mentions that the developers are working on the item and improving its functionality in-game.Note: The Fortnite Chapter 3 Season 4 leaks mentioned in this article may or may not come to fruition and are subject to change.
